Understanding Superfloc's Mechanism
Superfloc polymers are designed to efficiently remove suspended solids from water. They achieve this through a specific mechanism:
- High Charge Density: These polymers possess a high density of positive charges. This is crucial for their interaction with negatively charged particles suspended in water.
- Destabilization: When Superfloc polymers come into contact with suspended solids, their positive charges neutralize the negative charges on the particles, causing them to destabilize.
- Aggregation: The destabilized particles then clump together, forming larger aggregates called flocs. This aggregation process is facilitated by the polymers' ability to bridge between multiple particles.
- Removal: These flocs, now significantly larger, are easily removed from the water through sedimentation or filtration.
Key Factors Influencing Superfloc's Performance
The effectiveness of Superfloc is influenced by several factors:
- Dosage: The amount of Superfloc used directly impacts the extent of aggregation and removal of suspended solids.
